Hi, Hopefully someone can help. I'm sure this point will have come up in the past but I have been searching the archives and can't seem to find answers to every question that I have. When I run an fMRI second level analysis (e.g. one sample t-test) in SPM5 and get the statistical map I can choose a voxel that I am interested in and plot a graph of the contrast estimates and 90% confidence intervals via the GUI. I want to draw my own graphs with a different program. My question is what do I type in the matlab window if I want to see the values used to draw the graph? If I type "y" I get the values used for each person. Is this correct? If I type "beta" I get the average value (across people) which corresponds to the value on the y-axis of the plot. Correct? What about the Confidence intervals? Surely they are stored somewhere in a similar manner and can be accessed by typing something similar? Also do the units of the graph show the percentage signal change for the contrast that I specified? Thanks in advance. Will
